Supplementary materials for the paper: Gao, R., Liu, H., Bazilinskyy, P., & Martens, M. (2025, September). Designing Multi-Modal Communication for Merge Negotiation with Automated Vehicles: Insights from a Design Exploration with Prototypes. In Adjunct Proceedings of the 17th International Conference on Automotive User Interfaces and Interactive Vehicular Applications (pp. 40-46).Supplementary materials include Arduino code for simple physical interfaces and video stimuli that depict merge scenarios from a driver’s perspective with the corresponding visual HMI (e.g., HUD) where applicable.
